隐私政策
你的记录以本地数据为基础。启用 iCloud 同步后，相关记录和附件会通过 Apple CloudKit 保存在你所用 iCloud 账号的私有数据库中。关闭同步不会删除已有的本地或云端数据。
1. 本地数据与权限
Threads 在设备上保存记录正文、清单状态、图片和文件附件、Thread 关联、编辑草稿及必要的设置。搜索和关联建议使用本地数据处理；当前版本不将正文交给第三方生成式 AI 服务。你导入的图片、文件和分享内容会成为本地记录或待导入内容。
语音输入只在你主动使用并授权后访问麦克风，使用设备端转写，不保存录音。你可在系统设置中撤销权限。导入、导出和备份使用你选择的文件或系统提供的选择界面。
2. iCloud 同步
同步由 App 内的 iCloud 同步设置控制。启用时，App 会处理 iCloud 可用状态、账号范围标识、设备副本标识、同步进度和校验信息，以在设备间安全传递记录。上传的数据可包括正文、时间、清单状态、关联与操作历史、附件原件及其元数据。免费版本可上传；从 iCloud 接收记录与附件属于 Pro 权限，具体可用性以 App 中说明为准。
CloudKit 由 Apple 提供，并适用 Apple 的服务条款及隐私政策。Threads 不要求你向我们提供 Apple 账号密码。同步不是独立的历史备份；建议对重要数据另行导出备份。
3. 订阅与付款
购买由 Apple App Store 和 StoreKit 处理。App 使用经过验证的产品、交易、到期和撤销状态判断 Pro 权限；我们不通过 App 收集支付卡号。恢复购买与管理订阅使用 Apple 提供的机制。价格、试用资格和计费信息以 Apple 的购买确认界面为准。
4. 诊断与支持
App 会产生用于定位故障的本地诊断，例如版本、同步阶段、计数和错误类别。支持诊断由你主动导出和发送；发送前请检查内容。我们会处理你通过电子邮件提供的邮箱、描述和附件，以回复问题，并仅在处理请求或履行必要义务所需期间保留。请勿附带密码、验证码或与问题无关的私密内容。
当前 App 未集成广告追踪 SDK，也不出售记录内容。打开外部链接后，对方网站可能记录访问所需的网络信息，请查看该网站的政策。本法律页面不包含表单、广告或分析脚本；实际托管服务仍可能处理提供网页所需的网络日志。
5. 保留、删除和你的选择
你可查看、编辑、导出和删除自己的记录。记录删除可能是可恢复的逻辑删除；为恢复与同步一致性保留的历史不等于即时从所有存储中抹除。备份和已导出的副本需要分别管理。关闭同步不撤回此前已上传的内容；卸载 App 不保证删除 iCloud、系统备份或你另存的文件。
可在 App 设置中关闭同步，并通过 Apple 的 iCloud 存储管理界面管理适用的云端数据。操作前请备份，云端删除可能影响其他设备。涉及支持邮件的信息，可联系上述邮箱请求访问、更正或删除；我们会说明能处理的范围。我们不能代替你登录 iCloud、恢复 Apple 密码或删除你自行保存的备份。
6. 变更与联系
若数据处理方式变化，我们会更新本政策及版本日期，并按适用要求提供通知或取得许可。隐私问题请联系 catcarp@163.com。
Privacy Policy
Local-first records
Threads stores notes, checklist state, images, files, Thread relationships, drafts and settings on your device. Search and connection suggestions process local data. The current version does not send note text to third-party generative AI services. Importing selected files or shared content adds them to your local records or import inbox.
Voice input uses the microphone only with permission when you invoke it, transcribes on-device and does not save recordings. Permissions can be revoked in system settings. File import, export and backup use files or locations you select.
iCloud
When enabled in the app, sync uses Apple CloudKit and your iCloud account's private database. Content can include note text, dates, checklist state, relationships, operation history, attachment originals and metadata. Account-scope identifiers, replica identifiers, progress and integrity information support synchronization. Upload is available without Pro; receiving notes and attachments from iCloud requires Pro, as explained in the app.
Apple's services are governed by its terms and privacy policy. We do not ask for your Apple Account password. Disabling sync does not delete data already stored locally or in iCloud. Sync is not a separate historical backup.
Purchases and support
Apple and StoreKit process purchases. The app uses verified product, transaction, expiration and revocation information to determine Pro access, without collecting payment-card details. Apple determines prices and trial eligibility shown at purchase.
Local diagnostics may contain versions, sync stages, counts and error categories. Support exports are sent only when you choose to export and share them. Review them first. We use your support email, description and attachments to address your request and retain them only as necessary for that purpose or applicable obligations. Do not include credentials or unrelated private notes.
The current app has no advertising-tracking SDK and does not sell note content. External sites have their own privacy practices. These legal pages contain no forms, advertising or analytics scripts; their hosting provider may process network logs needed to serve them.
Control and retention
You can view, edit, export and delete notes. Deletion may be recoverable logical deletion; retained recovery or sync history is not immediate erasure from every store. Manage exported files and backups separately. Uninstalling does not necessarily remove iCloud data, system backups or exported copies. Manage applicable iCloud data using Apple's storage controls; back up first, as deletion can affect other devices.
For privacy requests, corrections or deletion of support correspondence, contact catcarp@163.com. We will explain what we can process; we cannot sign into your iCloud account or remove copies you hold. Changes to data practices will be reflected here, with notices or consent where required.
